Abstract
Highly ordered pore mesoporous silica composites, like SBA-3 and hydroxyapatite (HaP) nanocrystals,
characterized by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron
Microscopy (SEM), Transmission Electron Microscopy (TEM) and textural properties, were successfully applied to
remove fluoride from contaminated water. The proposed procedure to prepare HaP/SBA-3 was successful, which
acts as supports to anchor the HaP crystals, in nanometer-scale (<2 nm), with higher fluoride retention from
contaminated water. The free OH- groups of HaP nanocrystals, within the host, facilitated the high-performance
fluoride trapping. The fluoride retention activity was much higher than that of pure HaP and the composites
HaP/SBA-15 and HaP/MCM-41.
